The M18 configuration brings the P320's modular FCU system together with a 3.9 inch compact-length barrel and coyote tan finish to reflect the U.S. military issue sidearm. This example is chambered in 9mm Luger and ships with two 21-round magazines for a 21+1 capacity. The standard commercial M18 pack-out includes one 17-round and two 21-round magazines; the 17-round magazine is not included with this pistol.
Controls are practical and user-focused, with an ambidextrous manual safety and ambidextrous slide catch levers, plus a left-side magazine release. The curved trigger and striker-fired action provide a consistent trigger press.
The slide is equipped with front and rear serrations for confident manipulation. Sights consist of a front post with a single dot and a square-notch rear mounted on a removable plate, along with a removable rear sight/plate assembly.
The coyote tan polymer frame integrates a three-slot Picatinny accessory rail for lights or other rail-mounted accessories. Made in the USA, this carry-size P320 M18 balances carry-friendly dimensions with full-capacity magazines.
